Interlocked tube and plate utensil handhold and method of making same

ABSTRACT

Rigid handhold structure comprising a metal tube handhold unit and a flat metal plate utensil-engaging unit disposed at right angles to the handhold unit and having an aperture receiving the end portion of the tube, the joint between the two units being rendered rigid by reducing the diameter of the end of the tube to form a shoulder at one side of the plate and expanding the section of the tube inserted in the aperture, and subsequent flaring the tip of the tube. Preferably the edge of the plate aperture is recessed and the portion of the tube in the aperture is ridged to enter the aperture recess.

2 Claims, 10 Drawing Figures INTERLOCKED TUBE AND PLATEUTENSIL HANDHOLD AND METHOD or MAKING SAME The invention involves structure disclosed inpart in my patent application Ser. No. l62,l60 filed Jul. 13, 1971.

The main object of the invention is to produce a unit comprising a rigid tubular handhold and a head formed of plate metal without using expensive silver solder or expensive machining or other operations, thus materially reducing the cost of the unit.

In the accompanying drawings illustrating the invention:

FIG. 1 shows the invention embodied in a handhold applied to a cast metal C-shaped handle detachably secured to a beaker. I

FIG. 2 is a detail section on line 2-2 of FIG. 1 and drawn to a larger scale.

FIG. 3 shows two spaced die parts used in shaping the handhold tube and includes a section through the end portion of the tube before it is shaped by the die.

FIG. 4 is a section on line 4--4 of FIG. 5 after the die has shapedthe tube end portion.

FIG. 5 is a side view and sectionon line 5-5 of FIG. 4 and indicates the initial tapering of the tube end.

FIG. 6 shows the tube end portion and the web plate of the utensil head applied thereto in the first step in assembling those parts.

FIG. 7 showsfthe same parts, reversed top for bottom,

with a rolling tool inserted in the tube end portion to spread the same in the aperture in the head web.

1 FIG. 8 shows the subsequent flaring ofthe projecting terminal of the tube.

FIG. 9 similarly illustrates a later cupping of the tub terminal.

FIG. 10 shows the staking of the tube ribs in a final operation on the tube terminal to more'tightly fit it into the notches in the head web.

The handhold tube 11 is of light gauge metal and one end portion 12 is defirmed by pressure between the two die parts l3, l4 thrust apart by springs '8 (FIGS. 3, 4), and forced together by rotating the nuts of bolts B to compress the tube end portion '12 to a reduced diameter. This produces a rounded shoulder 15 on the tube and also produces diametrically opposite ridges or tapered ears 16 (shown exaggerated) on the tube end portion and extending lengthwise of the tube between shoulder 15 and the tip of the tube. Ears 16 (FIGS. 5, 6) merge adjacent shoulder 15 with the full diameter body of the tube and taper inwardly throughout their length from a maximum outside dimensionequ al to the full diameter of the tube to a minimum diarneterat their other ends equal to that of the reduced diameter tube end portion 12. g

The tube tip isthen inserted through a circular aperture in the web 17 of a channel-shapedhead, said aperture having notches 18 (FIGS. 7, 8) at diametrically opposite sides for receiving cars 16. The narrow outer ends of the ears enter the notches and interlock the head and the tube end portion. 7 I

If the diameter of distance across the aperture in web 17 at the notches is slightly smaller than the diameter of the outer tip of the tube acrossits ears, pressing or hammering the tube into the web (FIGL6) will form an elongated friction joint between these parts. When assembled there is a 90 degree angle between thetube axis and the plane .ofweb 17.

' tool 20 (FIG. 7) into the end of the tube and expanding the same to incline the tube wall in accordance with the rollers. 'Rotation of the tool tends to compress and harden the metal in the tube.

The projecting part of the end portion 12 of the tube may then be flaredat21 by a tool 22 (FIG. 8), and then cupped by a tool 24 (FIG. 9) and then a staking tool (FIG. 10) with a flat blade 26 engages the recesses 16a on the inner faces of the ears and spread the latter to firmly seat in notches 18 in web 17 throughout the thickness of the web. FIGS. 8, 9 and 10 indicate a block 39 which supports web 17 against the thrusts by the respective tools. This assembly effects the objects stated above and adapts the structure for its intended purpose without further treatment or operation.

FIGS. 1 and 2 of the drawings show the unit applied to the upright shank 28 of a cast metal C-shaped handle. The handle has hollow arms 29, 30 with arcuate terminals 31 fitting against the beaker side wall. Fingers 17a on the ends of the head jaws seat against lugs 32 on handle shank-'28. A flexible band 33 is looped about shank 28 and its ends 34 are inserted in tube 11 and are apertured to receive a hook 35 on the end of a square drawbar 36 with its corners threaded into a washer 37 fixed in tube 1 l. A takeup nut 38, rotatable in the outer end of tube 1 1, seats against washer 37 with a threaded aperture for the shaft and may be actuated to move the drawbar to the right and thereby tighten band 33 about shank 28. If the nut is turned in the opposite direction it will loosen the band and if the nut is screwed off of the drawbar the handle may be disengaged from shank 28 and applied to another device.

A similar handhold 41 is applied to the upper end of shank 28 and a takeup nut 40 mounted in the outer end of the handhold controls a drawbar (not shown) attached to a band 42 passing through hollow arm 29 and surrounding the beaker. The two handholds 11, 41 may be grasped tightly between the users palm and fingers with the latter well spacedfrom the beaker and the cast metal handle.

Anothertakeup nut 43 is mounted directly on the outer face of handle shank 28 and controls a drawbar (not shown) similar to drawbar 36 but attached to a beaker-enclosing band 44. Another tubular unit with band and nut as shown at 41, 42 and 40 may be substituted for the parts applied to the lower end of handhold 28 and the assembly 11, 33 omitted.

Other combinations of the handhold, band and takeup structure may embody the invention as expressed in' the accompanying claims.
